Low cost Air Quality sensor

This version includes a Fan added to the PPD42N sensor to increase the air flow, a 10K resistor from pin 5 of the sensor to GND to improve measure accuracy and the addition of sensor SHT1x to measure humidity and temperature.

The sensor is here but it seems it will require some calibration. It currently shows some PM10 data but a lot of Zeros in PM 2.5 data. Some research has shown that I need to add a case and a fan.

Currently taking measures of Temperature and Humidity. Cancelled measures of CO, MQ7 sensor requires modifications to be more accurate. Still waiting for PM2.5 sensor.
